Experimental Study on Roasting Cyanidation of an Iimported Arsenic-containing Gold Concentrate
An imported arsenic-containing gold concentrate contains 20 g/t gold,50 g/t silver,0.15%copper,1.3%lead,8%arsenic,25%sulfur and 0.35%carbon,which is a typical difficult-to-treat complex gold concentrate,and the gold recovery rate after roasting,acid leaching,grinding and cyanide is not ideal.After the trial was carried out in proportion to other concentrates,the gold recovery rate increased significantly.The results show that under the premise of unchanged test conditions,the gold content in the obtained cyanide slag is significantly reduced by combining suitable concentrates,which provides a new attempt to improve the recovery rate of gold in arsenic-containing gold concentrates with complex composition.
